This invention relate s to mechanical movements, andparticularlythatbranch of mechanical movements pertaining to quick return motions. p

The invention has for an objecttheQprovision of a devi ce incorporatingthe mechanical movement which is simple in construction and positive inits operation.

In practicing the invention we provide a device applicable in one'of itsembodiments to pumps, such as usedtordelivering gaso line, oil' and'similar "fluids, and this def vice is adapted to actuate the plunger fordeliveringsaid fluid- VYhen utilizing such a pump it is customary toprovide some} means for raisingthe plunger of the pump. This isaccomplished by either turning a crank handle or by other mechanicalmeans. It a crank handle is utilized the crank handle is turned acertain number of times in one direction to raise the pump piston, and areverse movement of the handle'allows the pistonto descend. It isanobjectof our inventio n' to incorporate the particularmechanicalmovement to be described in a suitable device with the handle of thepump and the pump so that a certain number of turns of the handle in onedirection will raise the pump piston, and a reverse turning of thehandle will lower the piston .with a less number of turns of thehandlethan was re-.

quired to raise the piston. For instance, it might require twe'lve turnsofthe handle to entirely raise the piston and three turns of the handlein a reverse direction to lower the piston. This operation isaccomplished without the operator of the pumP doing more than turningthe handle in one direction or the other. I V

= and the same number of turns in an opposite directio will lower therack bar the same distance. It is the purpose of this inventiol to allowthe racl: bar to be raised by a definite number of turns or the handleto its extreme limit, and a reverse turning of the handle 10 will lowerthe racl: bar

with a correspondingly lesser number of" opening 1 1- through which therack bar 8 passes. The side wall 12 provi'f ith an opening 15 and abearing plate 16 has a part received within said opening and a partadapted to engage the outer surface of the side wall 12 and to be heldthereto by suitable securing means such as screws. The bearing platev isprovided with a bore 1'? and the side wall 11 provided with a bore inalignment, as at 18, with anddirectly opposite the bore 17. A shaft 19is received within the borescl? and 18 and spans the One end of saidshaft 19 carries the handle member 10. Carried upon the shaft 19 and atan intermediate portion thereof, is a member 20 provided with threads21. in the drawing said threads are shown as external quadruplesquare-cut threads. The member 20 is either fixed to the shaft 19 so asto turn with the shaft or it is an integral part of the shaft 19, asillustrated in Figure Loosely carriedoon the shaft 19 and within thehousing a is a pinion 22 and a gear That portion of the side 11surrouncing; the bore is enlarged so as to form a bearing for the gear23. providedrith an enlargen'ient at so as to act asva bearing for thepinion 22. Likewise carried on the shaft 19 and between the member 20,the pinion and the 23, are collar members 25 and 2?. which collarmembers are each united to the shaft 19 by suitable means such as pinsthrough the same and engaging with the shaft. The pinion 22 and the areeach provided with outstanding projections or lugs 27. A nut 28 providedwith internal threads is received upon the member 20, Said nut islikewise provided at each end. thereof with. outstanding lugs A frictionmember Z) is carried upon said nut. 28 said friction member comprisestwo split rings 80 and 31 with each of said split rings provided withoutstanding lugs 32 and 33 and the said lugs provided with screwthma dedbores 34- and 35 adapted to receive The bearing plate 16 is also' a boltObviously a turning of the bolt 36 will tighten the split ring membersupon the nut 28 so that it will more securely engage the periphery ofthe nut. The split ring 31 likewise carries an outstanding fur-rated.member 37. The side 12 carries an inwardly projecting rod 38, and bothlegs and of the furcated member 37' grip opposite sides of said rod 38.Obviously this construction will not permit a rotation of the member 7)when the handle member 10 is turned so as to rotate the shaft 19 andconsequently cause a rotation of the member 20 which in turn will causethe nut 28 to reciprocate or move in one direction or the other relativeto the member 20. If it were not for the member 7) the nut 28 would ofcourse rotate. Obviously if the handle member were rotated clockwise themember Z2 and the nut 28 would be given a translational movement to theleft looking in the plane of Figure 2 whereupon the projection 29 wouldengage'the projection The gear 23 would not of necessity rotate as it isloose upon the shaft 19. A reverse movement of the handle 10 wouldshiftthe nut and the member 5 to the right so that the projection 29would engage'the projection 27 ofthe gear 23 and tend to retate saidgear in step with the turning move- .ient of the shaft, leaving thepinion 22 free. I

To make use of the mechanism, which is described, so to actuate orreciprocate the rack bar 3, there is likewise carried within thehousing; a a second shaft 4L1. Loosely carried upon said shaft is apinion 42 provided with two hub portions, with the teeth of said pinionin mesh. with the teeth of the rack bar Fixedlvcarried upon the hubportions of the pinion 42 are two gears 43 as the pinion 42 is rotatedby movement of the rack bar thegears 43 and 4-4 are likewise turned. Ifthe gear 4:4: in mesh with the pinion 22 and the gear 43 in mesh withthe gear 23. one or the other of said trainsv of will be actuated upon aturning: of the. handle 10 in clockwise or coiinter-clockwise direction.-The first train of includes the pinion 22 and the gear 4ft.andthepinion 42: the second train of ars includes the pinion 42 and thegears 1.3 and If the id is in a ratio of 3 to 1 with respect to thepinion 22 a turning of the handle 10 clockwise will slowly raise therack bar 3 If the handle were rotated in an opposite direction themember Z2 and the nut 28 would move to the rightso that the big 27 ofthe gear 23 and the lug 29 would engage each other and permit rotationof the gears 23 and 43 so as to lower the rack If the gears 23 and 43are in a 1. to 1 relation, obviously then the number of turns of thehandle necessary to lower the racl; bar 3 would be materially reduced.

A'device of this character will be extreme ly useful in gasolinestations,inasmuch as the gasoline tanks of motor vehicles may be quicklyfilled without undue effort on the part of the operator.

It will thus be seen that the invention contemplates a suitable clutchwhich consists of the member 6, the nut 28 and the member 20, and whichclutch is adapted to actuate one or the other of two trains of gearshaving different gear ratios, and which gears in turn are adapted toactuate another member to cause said member to have a slow movement inone direction and a quick return movement in the other direction.

It is believed that the operation of the device will be obvious from thedescription above given.

It is obvious that many changes and variations and modifications may bemade in departure from the particular description and showing of theaccompanying drawing, in adapting the invention to varying conditionsand requirements of use and service, without departing from the truespirit of the inven tion.
